Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
Since both expressions are equal to y, you have to equal both expressions like this:
Now you can solve the equation:
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result
So, the answer is x=10 and y=-1

Answer:
The pressure is
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or
In this problem we have
where
V is the volume of a gas at a constant temperature
P is the pressure
we have
For ,
step 1
Find the value of k
substitute the values of V and P
The equation is equal to
step 2
Find the pressure when the volume is 125 cubic inches
For
substitute in the equation and solve for P
